When to use Ember.Namespace?

Design
1

I feel this construct is outdated in the age of ember-cli that automatically put your add-ons in an add-on namespace.

Is there a case where Ember.Namespace is still needed?

It is still used. See: https://gist.github.com/jayphelps/8432362

I don’t think what’s written in the gist is really applicable as it is written over a year ago. It doesn’t show modules written as ES6 modules.

ember-cli automatically compiles apps under an AMD module namespace. You can extract shared code as add-ons if you’re just looking for code reuse. The add-ons are automatically compiled under a different AMD module namespace.

So if codes are already namespaced by AMD modules, why do we still need Ember.Namespace?
